The laptop, which weighs in at 4.9 pounds and 1.1 inches thick, is somewhat larger than similar devices on the market today.

As Liliputing's Brad Linder notes, the Satellite P50t is too thick to count as an Ultrabook and lacks a Solid State Drive (SSD).

"[Nevertheless], Toshiba isn’t the only company working on a 15 inch notebook with a 4K Ultra HD display. Asus is also apparently working on a Zenbook NX500 laptop with an aluminum case and Bang & Olufsen audio," said Linder.

"Samsung, Lenovo and others also offer a number of laptops with only slightly less impressive 3200 x 1800 pixel displays."
